I think you're looking for a depth of equivalence that I wasn't suggesting was there.
To further muddy things, you should know that explosions themselves don't produce the responses they do just in veterans. High-bandwidth sounds trigger an autonomic response as soon as they hit the brain stem- long before the cortex has a chance to think "I recognize that as an explosion", the brain stem said "HOLY SHIT SOMETHING IS HAPPENING". This mechanism is observed in rape and abuse survivors as well as veterans.
